Thanks for testing Guillaume. Looks like I did not attach the latest version of the patch. Anyway, I will cleanup the patch and push it soon.

Thanks @Pantxo!

When I first applied the patch, I got an error at compilation:

  CXX      libgui/graphics/libgui_graphics_libgui_graphics_la-ObjectFactory.lo
../libgui/graphics/Figure.cc:544:52: error: no ‘void QtHandles::Figure::showMenuBar(bool, int)’ member function declared in class ‘QtHandles::Figure’
   Figure::showMenuBar (bool visible, int h_previous)

I then removed the following from Figure.cc:

  Figure::showMenuBar (bool visible, int h_previous)

and it compiled fine. With the patch, the issue I mentioned disappear and everything seem to be working fine! Thanks!

@Guillaume: I attached a patch that fixes the original issue for me (and simplifies the "menubar" property handling). Can you test it?

(file #45041)

Confirmed, looks like I did not check this case ... I'll look into this.

The workaround for the time being is to change the "menubar" property after the figure has been constructed.

hf = figure ("position", [650 350 620 500]);
set (hf, "menubar", "none");

Since recently in dev (since 25878:bb4af245dff7 perhaps), the size of a figure is not correct when MenuBar is disabled. Running the following:

F = figure ('Position',[650 350 620 500], 'MenuBar','figure');
get (F, 'Position')

F = figure ('Position',[650 350 620 500], 'MenuBar','none');
get (F, 'Position')

displays a second figure smaller in height (the drawable area):

octave:1> F = figure ('Position',[650 350 620 500], 'MenuBar','figure');
octave:2> get (F, 'Position')
ans =
   650   350   620   500
octave:3> F = figure ('Position',[650 350 620 500], 'MenuBar','none');
octave:4> get (F, 'Position')
ans =
   650   350   620   500
octave:5> get (F, 'Position') # asking again manually
ans =
   650   350   620   410

While physically smaller, the returned Position of the second figure is the asked one. If one then asks for the Position again, the return position now differs and seem to correspond to the one actually used. The drawable area seems to have the asked Position minus the size of all of the menus (top and bottom).
